Undercarriage Rust Prevention?

[Hsnopi]

Hello all,
I did a search on undercarriage rust here and see Fluid Film is well recommended.

There is surface rust on my 2015 JKU. Is Fluid Film still recommended? We honestly don't offroad but I also don't want to get frame damage.
Thoughts?
Thanks

I use fluid film. I'm gettin ready to clean the underside and spray it down again.

how often do you need to do it?

I do it once a year. Seems to be working good. This past winter was bad with the salt so I want to clean everything good and get another coating on just to be safe.

would it be more effici3ent to use a rustoleum based paint for longer life?

I used Loctite Extend Rust Neutralizer to convert the surface rust into a paintable surface. Then sprayed the whole underside with Fluid Film.
